- Specification of Letters Patent. Pgtgtgd BQ@ 2579 M9210' ,application led February 7, 1920. Serial No. 357,052.

To all whom it may cio/noem Be it known that l, `W1LL1AM3 HENRY '(lotlies-Wringers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,'forming a part of this specification.

rlhis invention relates to improvements in clothes wringers, the main object being to produce a strong and simple wringer structure provided with a simple releasing device whereby vthe pressure at the wringer rolls may be easily and quickly released.

Figure l is a front elevation, partly in section, illustrating a wringer embodying the features of this invention.

Fig. Il is a vertical section taken approximately Onthe line-l-I of Fri l.

To illustrate the invention a wringer frame comprising upright end members 1 forming housings lfor the bearings 2 and 2 in which the wringer rolls 3 and 3f are rotatably mounted, said rolls being provided atl their ends with journals engaging the bearings 2 and 2 respectively. The wringer frame alsoy includes horizontally disposed uppermembers 4 integrally connected to the upright members 1.

Compression springs 5 are interposed between the upper bearings 2 and a tie-bar 6. Screws 7, acting upon end portions of the tie-bar 6', may be adjusted to vary the pressure of the springs v5v. These springs allow the upper roll 3 to move toward and away from the lower roll and they tend to force the upper roll into engagement with the lower'roll.

To illustrate the preferred form of the in-l vention I have shown a thrust-receiving bar 8 arranged between the rigid frame members 4 and located immediately above' the tiebar 6. Nuts 9 are secured to the end portions of the thrust-receiving bar 8 to receive the adjusting screws 7 It will now be understood that the spring pressure is transmitted through the end portions of tie-bar 6 to the lower portions of screws 7, and thence to the nuts 9 in the thrust-receiving bar 8. If the bar 8 is held in a fixed position, the springs 5 will be retained under pressure, and the screws 7 may be adjusted to vary the have shownpressure. However, if the thrust-receiving lb ar 8 1s released, and permitted to move vertically, the spring pressure will be immediately relieved, and the pper wringer roll 3 can I,then be1 freely moved away from the lower roll.

1 will now describe the breakable bridge whichenga'ges the top face of the thrust recelvmg bar 8 to normally retain said bar in a fixed position. rlhis bridge preferably comprlses a lpair of abutment wings 10 located between the upper frame members 4 and pivotally connected thereto as shown at 11, said frame members 4 being. slotted to receive pivot loops which extend from the wlngs 10, and the axes ofthe pivots being parallel with the wringer rolls.--Each wing 1 0 1s approximately L-shaped in cross section to provide a horizontal abutment face engaged by the Vthrust-receiving bar 8, and an upwardly'extending flange adapted to be engaged by a releasing clip, as will be pres. ently described.

The wringer framev preferably includes an upper rigid framememberl 12, located between the frame members 4 and having its ends rlgldlyattached to the upright frame members 1. The releasing clip is in the form of a lever pivoted at 13 to the rigid frame member l12 and provided with "a forked lower end 14 st-raddling the upper-portions of the wings 10. This lever has an operating han;

dle 15 which may be depressed to release its forked end 14 from the wings 10. 16 designates a spring tendingtoretain the lever in the position shown in the drawings. The' -rlgld upper frame member 12 lies between the vwings 10, and the clip formed by the forked end 14 coperates with the wings 10 to form a transverse bridge which extends across the upper portion of the wringer frame. This bridge is normally subjected to the spring pressure which tends to throw the thrust-receiving bar 8 in an upward direction. To break the bridge, it is only necessary to depress the releasing member 15 (Fig. '-1) thereby releasing the forkor clipl 14 from'the'wings 10'. ln this event, the pressure transmitted throughl the thrust-receiving bar` 8 will cause the wlngs 10 to turn on their ivots, and the upper edges of the wings. wi l move as indicated by ,arrows in Fig. l'l so as to engage the frame 'members'4 which limit the motion of thewings, and

Y which. permit said wings to serve as stops I` claim:

1. In a Wringer, a frame, a pair of Wringer rolls, yielding means forl forcing one of said rolls toward the other, a movable thrust-receiving member mounted in for limiting the `upWard motion of thrustv said frame and subjected to the pressure of said yielding means, and a breakable bridge extending across said frame and coperating With said movable thrust-receiving member to retain said yielding means under pressure, said breakable bridge including a pair ofv wings, a pressure releasing device spanning the inner margins of said Wings and pivots connecting the outer margins of said Wings to said frame, the axes of said pivots -being approximately parallel With the axes of said vvringer rolls.v

2. In,a Wringer, a frame, a pair -o'f wringer rolls, ylelding means for forcing one of said rolls toward the other, a` movl able thrust-receiving member subjected to the pressure of said yielding means, and a breakablerbrdge extending across said frame and coperating with said movable thrustbreakable bridge extending across lsaid frame and coperating with said movable thrustreceiving member to retain said yielding means under pressure, said breakable bridge comprising a pair of Wings, H -shaped in cross section, pivots securingv said Wings to saidl frame, the axes of said pivots being approximately parallel with said Wringer rolls, and l a pressure releasing clip* connecting said Wings to prevent breakage of said bridge.

4. In a -Wringer, a frame, a pair of wringer rolls, yielding means for forcing one of said rolls toward the other, a movable thrust-receiving member subjected to the Monaca' i 5. In a Wringer, a frame, a. pair lot" Wringer rolls, yielding means for Jorcing one of said-rolls toward the other, amovable thrust-.receiving member subjected to the 'pressure of said yielding means, a. transverse bridge spanning said frame and cooperating With said movable thrust-receiving member to retain said yielding means under pressure, said transverse bridge comprising a pair of Wings pivotally secured to sald frame and a retaining clip pivote'd to said frame and engaging said Wings Vto prevent breakage of said transverse bridge, and an operating member associated with said retaining clipby which to remove said clip from said Wings. i

6. Ina Wringer a frame comprising up.- right end members, horizontally disposed upper members uniting said end members upper members, all of said members being rigidly secured together, Wringer rolls, yielding means forcing one of said rolls toward the other, a movable thrust-receiving member subjected to the pressure of said yielding means, and a breakable bridge spanning the space between said upper members and .cooperating with said movable thrust-receiving member to retain said yielding means under pressure, said breakable bridge comprising Wings located at opposite sides of said intermediate member and pivoted to said upper members, and a clip pivoted to said intermediate member and straddling said Wings to prevent breakage of said bridge, said clip having an 'operating member whereby it may be released from Said Wings.

In testimony that I claim the foregoing I hereunto afix my signature.
